Well, this is verrrry old now so I'd be more than happy to send you the file but I don't have it anymore; however, I can make you an example fla of the same thing if you like, what version of flash/actionscript would you want it in?

It Was made a while ago, Using Actionscript 2 in MacroMedia(now Adobe) Flash 8 Pro.

Its effectively a series of bars each with a 1-100 frame animation cycling through colours, the first bar is scaled with the _x property of the mouse and coloured by changing the frame of the clip 1 through 100 depending on the position of the -y property of the mouse; the subsequent bars inherent their position and colour from a matrix(2Dimensional Array)of their predecessor.
